Circular No. 4181 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Postal Address: Central Bureau for Astronomical Telegrams Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. TWX 710-320-6842 ASTROGRAM CAM Telephone 617-495-7244/7440/7444 1986 DA S. Nakano, Tokyo, reports that M. Kizawa, Shizuoka, has discovered a minor planet of unusual motion. The positions (measured from Kizawa's films) and orbital elements below have been determined by T. Urata. The ephemeris magnitude is visual (V), derived according to the new IAU precepts described on MPC 10193. 1986 UT R.A. (1950.0) Decl.
